OuV opposite 'aides of the twoistnnds of rolls are conveyor tables 1.2und 13, each com lbrisingrmseries of 'positively driven com reyer rolls14 and 15 receiving their motion l'from the eountershafts 16 unrllf,connected with reversible motors, not shown, by which the direction ofthe rotation of the conveyor rolls may be changed at will. Upon eael'rSide of the Conveyor tables 12 und 13.?- are wheels 1r carrying fndlossbelts 19 provided with lugs 29. The sprocket Wheels upon one sidegof theconveyor liable 12 are carried upon a coln'tershuiit 21, preil ublbydrivenby un independent motor, und the sprocket wheels upon one side ofthe envoyer table 13 are Carried upon. a oountersl'luft 22, preferablydriven by an independent motor.` l

The upper `or horirontz'rl` portions of the endless Chains 19 arecarried upon tracks, one of which is' shown at 23, Fig. 2, :whichmaintain y-the lhorizontal portions 4`of the chain in ai plane justbelow'the supporting.

veyer rolls are the inclines 25 over which.

`the blooms are moved by the lugs 20; `The inelines 25V consist oftriangular projections having vertical sides 26. l As the bloom reachesthe apex or highest point of the ineline 25,` it falls upon theverticalside 26,v

pausing the bloom to be turned one quarter turn.

In operation, the initial'V rolling unido Vmi by the'pass 10 in therolls 1, and is delivered upon the Vconveyer table 12. The bloom is thenmoved `sidevv'ise :icross the conveyor table 12 and over the inelines'25,-causingit toxbe turned one quarter turn `and brought into ulinementwith the pass 11 of the rolls 2'. The rotation of; the rolls inthe'conveyer tables is then reversed and the bloom ce1'-y ried throughthe vass 11 und delivered .il on .the eonveyer tab e 1 3.V The bloom ist en transferred sidewise by means of the chains 19 and lugs 20 intoallnement with the pass l' are rotated to carry the metal into positionto be transferred by the belts 19 and lugs 20. The conveyor rolls arethen stopped during the transfer and reversed to carry the metal intothe next succeeding pass of the rolls 1 and 2.

The reduction of the bloom is eected by the alternate rolling of themetal between the rolls l and 2, the bloom being turned one quarter turnafter each rolling. The

presentation of the bloom to and its delivery' from each pair of rollsand its sidewise transfer' from one pass to the next succeeding pass isdone mechanically and with sufficient rapidity to prevent the undue lossof heat.

I claim,

1. A lrolling mill comprising two stands of two high rolls placed instaggered relation to each other, with the rolls of each stand providedwith a multiplicity of passes for the consecutive-reduction of therolled metal alternately in said stands, witha reduction in the size ofthe asses from corresponding ends of the rol s in each stand,

whereby a uniform lateralmovement will transfery the rolled metal from apass in one vstand of rolls to the next consecutive ass in the otherstand of rolls, conveyer ta les on opposite sides of said stands ofrolls, common to al1 the asses in said rollsP means for rotating the rols in said stands 1n opposite directions, means for transferring therolled metal by a sidewise movement from its aline- `ment wlth a passinone stand ofrolls to an alinement'with a pass in the other stand ofro1ls,`a nde stationary incline having a vertical side interposed in thepath ofthe sidewise movement of the rolled vmetalwhereby'the metal isrotatedl a predetermined partial revolution duringsaid sidewisemovementi 2. A rolling mill comprisingtwo stands. of two high rollsplaced in staggered relation to each other, with the ro 1s of saidstandsjournaled at one end in independent housin s and with the otherand adjacent ends o the rolls journaled in a single integral housing.

3. A rolling mill comprising two stands of rolls running in oppositedirections, with their passes out of alinement, means for transferrinthe rolled, metal by a sidewise movement rom its alinement with a, passin one stand of rolls to an alinement with a ass in the other stand ofrolls, and means or rotating the rolled metal about its ow axis durinDated t 1914.
